Chinese Stock Screen for Volatility, Sharp Declines, and Recent Limit-Ups

Summary

This Chinese stock-selection note describes a screen combining daily price movement with recent limit-up activity. It selects stocks whose high-to-low range exceeds a threshold, whose current-day maximum decline falls between 4% and 5%, and that recorded more than two limit-up sessions in the prior ten days. The article frames limit-ups as a possible sign of market attention and uses price range and drawdown as rough measures of volatility and risk.

It supplies example indicator logic and a Python illustration, but no backtest, performance results, transaction-cost analysis, or rules for entering and exiting positions. The note cautions that the screen omits company fundamentals, industry conditions, and policy changes, and that limit-up events are uncertain. It suggests adding other price indicators and fundamental information, but does not evaluate those additions. The stated conditions and sample implementation are therefore a screening proposal, not evidence of a profitable or complete trading strategy.
